What is a TCR?
The Tariff Comparison Rate (TCR) is a rate for you to compare a tariff against another. It's a cost per kWh that a typical consumer would pay on that tariff. To work out the rate, we assume an average of kWh and then include the unit rates and standing charges. However, it's a guideline to help customers compare tariffs, it's not an actual price. The amount you pay will depend on your actual usage. Your current tariff's TCR is always printed on your bill or annual summary.

TCRs will vary by location, fuel type (e.g. gas) and payment method.

What is a TIL?
The TIL gives you all the information you need about a tariff in a standard format, to let you easily compare products. Each TIL is specific to the location of your property, fuel type (Gas or Electricity) and payment method.
